. It further has for its object an arrangement of a retaining strip-which interflts with the frame around the glass in. an edgewise direction to prevent unintentional transverse displacement and also which interflts with a circumferential mem-- her around the glass to prevent unintentional displacement of the retaining strip inwardly in a direction edgewise or parallel to the plane of the window, that is, displacement of the retaining stripout of its interfltting engagement with the frame around the glass.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

l designates the frame or any structure for 40 receiving a glass. 2 designates the window glass mounted in the frame. The frame I is formed with an internal circumferential recess, angular in cross-section, and having a side wall 3 forming one side of a channel for receiving the glass,

45 and a bottom 4. The other side of the channel is formed by a retaining strip to be presently described.

The glass 2 here shown is provided with a coacts with the side wall 3, bottom 4- and the re- 5 taining strip tobe described.

(01. ice-is) In the illustrated embodiment of my invention, the frame member in its entirety is formed of resilient compressible material, as rubber;

The frame member 5 is U-shaped in cross-section, or in the form of a channel and encircling 5 the margin of the glass pane, the member 5 engaging the side wall 3 and the bottom 4 of the frame I. v

The frame I is formed with an inwardly facing groove 8 located out of the plane of the window 10 and beyond the edge of the glass and being substantially parallel to the plane of the window, it being parallel in order to facilitate the insertion of the retaining strip or the base flange thereof.

I designates'the retaining strip, this having a 15 circumferential base' flange 8 for interfltting in the groove 6. The groove 6 and the flange 8 constitute interfltting means on the retaining strip and the frame I arranged to prevent unintentional transverse displacement of the 'retain- 2o ing strip: The retaining strip also includes a head or gbead portion 9 coacting with the ad- 'jacent side of the frame member 5. The adjacent side of the frame member 5 and the head 9 of the retaining strip are formed with inter- 25 fitting means arranged to prevent inward or edgewise unintentional displacement of the retaining strip out of the groove ll. Ashere shown,

the head 9 isni'ormed witha lengthwise groove ill for receiving a rib II on the adjacent side of 30 the member 5 interfitting in the groove. The rib and groove are preferably rounded. Likewise, the slde-3 of the channel and the contiguous side of the member 5 are preferably interlocked in a similar manner. The retaining strip is preferably of resilient compressible flexible material, as rubber, which, after the window is placed in position, is step by step interlocked in the groove 8 and with'the member 5, that is, the retaining strip is inched 40 into position and so placed that the abutting ends come close together. In order to permanently hold the abutting ends together against the displacement due to creeping or crawling of the retaining strip, screws, as l2, may be pro-' vided extending through the window frame and into the base flange 8 of the retaining strip near the abutting ends of the'retaining strip, or, as seen'in Figure 3, a flatclip l3'may be provided having prongs ll. When the glazing strip is placed in' position, the abutting endsmay be pulled outward sufliciently to place the clip lapping the flange 8 at the abutting ends with the prongs thereof hooked into the abutting ends, 5

and then the ends pressed down with the clip I thereon into the groove. 8.

In'window structures where the sash is slidable or can be opened and closed or raised and .5 lowered, the frame I, member 5 and strip 1 may be considered a compound sash consisting of the three parts I, 5 and "I. In window structures that are stationary, that is, can not be raised and lowered, the frame I might be considered the window frame and the member 5 the sash. When the sash is slidable, the rounding corners are squared asshown at I5 (Figure 1).

in placing the glass in position, the member 5, which is an endless band, is placed on the glass pane and is or may be under tension. The glass with the element 5 thereon is then placed in the frame I; then the retaining strip placed in position. In order to replace broken glass or for any other purpose, the retaining strip may be readily removed by displacing one end out of the groove 6 and then pulling the strip out of the groove. After the glass with the member 5 thereon has been replaced, the retaining strip may be replaced, as before described.

Owing to the groove 5 being parallel to the plane of the sash, the retaining strip may be easily placed in position, and further owing to the interflt between the retaining strip and adjacent wall of the member 5, the retaining'strip is held from inward displacement, particularly at the rounding corners of the frame I, where it would otherwise loop inwardly out of the groove 6.

In the construction shown in Figure 2, the circumferential member 5 is intended/ to fit accurately in the frame I, so as to interfit with the side wall 3 of the channel. Hence, when the retaining strip I is. placed in position and the head 9 thereof interfitted with the retaining member, there is no tendency due to shifting of the glass panel, and hence of the circumferential member 5 to work or shift the retaining strip relatively to the frame or in an edgewise direction out of the groove 5. However, glass panels intended to be the same size vary slightly in size and do not fit accurately in the groove of the circumferential member 5,. so that a tendency might develop for the member 5 to shift with the glass, particularly if the circumferential member is under tension around the glass, and cause the retaining strip I to shift slightly leaving a gap between the head 9 of the retaining strip and the edge of the frame I. Therefore, as seen in Figure 5, in order to eliminate this gap, the edge of the .wall of the frame I on the outer side of the groove Ii is provided with a rabbet 2D and the head 9 of the retaining strip formed with a groove 2| for receiving the margin 22 of the wall of the frame I atthe outer side of the groove 6, and also with a flange or rib 23 extending into the rabbet 20. Thus, in this construction, if the. circumferential member 5 does shift, and in so doing shifts the retaining strip I, because the head of said strip being interlocked with .the member 5, the flange 23 will close the gap.

cumferential member 5 may 'be placed around the glass but not under tension, so that the retaining member will accurately interfit in the channel of the frame I and-the head 9 of the re taining strip will accurately interfit with theretaining member and not be subject to any shifting tendency of the glass panel in the circumferential member or a shim or spacer strip S may be placed onthe bottom of the groove tocompensate for variation in the'size of the glass, and the circum- -drawn out or narrowed by the stretching so that ferential member may or may not then be under tension.

If a shim is not used and the glass is undersize, any shifting of the glass is inconsequential as it is cushioned on the circumferential member 5 and also is tightly held, or, in other words, is in airtight relation to the frame I and the retaining strip I, this being of importance in double windows having an air space between them. I

In Figure 6, in order that the circumferential member 50 may interfit with the retaining strip I0 and hold the retaining strip I0 from moving out of its groove 60, the head of the retaining strip and the adjacent wall of the circumferential member 50 are interfltted by means of a plurality of lengthwise barbs or corrugations 5I, preferably formed on the adjacent side of the circumferential member 50, and any one coacting with the head'QIl, so that the retaining striplO is held from working out of the groove 60 when once placed in the groove 60, by reason of the interfitting of the head 90 with the corrugations or barbs 5|. In Figure 6, the base flange B0 of the retaining strip a If! is also shown as formed with barbs BI coacting' with the side wall of the groove 60 and extending at such inclination as to resist or obstruct working of the retaining strip III out of the groove 60. The incline of these barbs 8| is such that any tendency of the retaining strip I0 to work out of the groove causes a slightwidening or expansion. To intentionally get the stripout of the groove, one end thereof is pried out of the groove and then upon stretching of the retaining member by pulling on the end, the base flange naturally the barbs come loose freely. These barbs 8| per se form no part of the invention but are similar to those shown in the application of Edward F.

' Chaffee, Serial No. 171,528, filed October 28, 1937.

In all forms of the invention, the retaining strip 40 is held from unintentional displacement out of the groove by interlocking with the circumferentiafl member.
